Move icore to blkfs The way is clear for complete stage1 bootstrapping on the RC2014 target! 2020-04-24 05:14:14 +10:00			`0xe800 CONSTANT RAMSTART`

Replace INITIAL_SP with PS_ADDR conf Now I struggle to remember why I ever did things they way I did. There must have been a reason... 2020-05-12 11:08:24 +10:00			`0xfffa CONSTANT PS_ADDR`

Use blk's boot.z80 2020-04-23 11:49:44 +10:00			`262 LOAD ( xcomp )`
xcomp: add overrides into a loadable block Makes xcomp.fs units shorter. 2020-05-14 03:33:24 +10:00			`270 LOAD ( xcomp overrides )`
Add CURRENT* and simplify xcomp 2020-04-10 02:01:08 +10:00
Use blk's boot.z80 2020-04-23 11:49:44 +10:00			`282 LOAD ( boot.z80 )`
Free some space for xcomp core low 2020-05-13 22:00:49 +10:00			`393 LOAD ( xcomp core low )`
Split icore in 2 parts The goal is to insert device drivers in between. 2020-05-09 11:47:03 +10:00			`: (emit) 0 PC! ;`

Update z80c.bin's LATEST during xcomp instead of using slatest 2020-04-26 12:02:44 +10:00			`( Update LATEST )`
xcomp: remove XOFF and use ORG and BIN( instead 2020-04-28 23:15:17 +10:00			`PC ORG @ 8 + !`
emul: bootstrap to stage2 from within Collapse OS! Big bootstrapping change which greatly reduces the role of the modern operating system in the bootstrapping process. 2020-04-27 00:15:35 +10:00			`," CURRENT @ HERE ! "`
Move core's blk to xcomp core (low and high) TODO: implement X['] so that I can remove those XCURRENT patterns. 2020-05-14 00:14:23 +10:00			`440 446 XPACKR`
Add a layer of indirection for KEY 2020-05-03 00:37:37 +10:00			`," ' (key) 12 RAM+ ! "`
xcomp: move all offset spitting to the end of the unit I'd like to move this code, along with all recipe contents, to blk/. It's easier if "emul-related" code is gathered at the same place. 2020-05-06 10:10:04 +10:00			`ORG @ 256 /MOD 2 PC! 2 PC!`
